Title:
HOT-MELT PRESSURE-SENSITIVE ADHESIVE, STRETCHABLE LAMINATE, AND ARTICLE
Document Type and Number:
WIPO Patent Application WO/2016/208701
Kind Code:
A1
Abstract:
Provided is a hot-melt pressure-sensitive adhesive that has sufficiently suppressed odor and can be applied evenly in a relatively low-temperature range. Also provided is a stretchable laminate having such a hot-melt pressure-sensitive adhesive. Also provided are articles including such a stretchable laminate. This hot-melt pressure-sensitive adhesive includes a Ziegler-Natta-based olefin resin, a hydrocarbon-based tackifier, and an oil component, wherein the adhesive force at 23°C, at a detachment angle of 90°, and a detachment speed of 300 mm/min on polypropylene spunbond nonwoven fabric having a basis weight of 19 g/m2 is 200 g/25 mm or higher, the adhesive force at 23°C, at a detachment angle of 90°, and a detachment speed of 300 mm/min on a stainless steel plate is 700 g/25 mm or higher, the melt viscosity at 160°C is 10,000 mPa⋅s or less, the melt viscosity at 140°C is 15,000 mPa⋅s or less, and the softening point temperature is 100°C or less.
